Alternative suture technique for anastomosis of veins with different diameters
No full textdiscrepancyMicrovascular anastomosis of vessels that differ in diametercan be technically difficult and time-consuming. Difficul-ties with positioning may lead to kinking or compression,and bleeding at the anastomosis can be a problem. Turbu-lence and sluggish flow in dilated vessels can predispose tothrombosi
Late onset complications secondary to polyacrylamide hydrogel-based filler for rehabilitation of HIV-related facial lipoatropy
Full text linkIn 2015 we reported our experience of a 5-year follow-up
study regarding the utilization of polyacrylamide hydrogel-
based filler for rehabilitation of HIV-related facial lipoatropy.
1 The outcomes of this study confirmed the safety and
efficacy of this noninvasive treatment as already stated in an
earlier report of 18-month follow-up period for that study
population.
Letter responds to comments on: Head bandage after otoplasty: How long should it be worn?
No full textOtoplasty is a surgical procedure often performed to
correct prominent ears, with the goal of normalizing their
shape and position. Various surgical techniques can be utilized
to create the antihelical fold if it is missing and/or to

Unusual Intraoral Necrosis After Hyaluronic Acid Injections
No full textascular compromise related to noninvasive facial
aesthetic procedures with filler is a major concern:
Although fillers are generally considered safe,
complications may occur. Facial vascular complications are
one of the most severe and feared immediate complications,
resulting from interruption of the vascular supply to the
area by direct injury to the vessel, compression of the area
around the vessel, and/or obstruction of the vessel (embolization)
by the filler material.
Aesthetic Surgical Pathway in Permanent Facial Filler Removal
No full textAlthough permanent fillers have been introduced in order to get long-lasting results, many studies have shown numerous severe and disfiguring complications. Nonsurgical procedures may mitigate those adverse events but the only way to remove the filler previously injected is represented by surgical excision. We present a pathway of facial surgical accesses to be performed achieving two goals: permanent filler removal and restore facial aesthetic balance. The proposed surgical accesses are already standardized in aesthetic surgical practice in order to avoid direct excision and unpleasant facial scar. A total of 231 patients underwent surgery for permanent filler removal and aesthetic restoration of the involved facial area, represented by forehead, glabella, nose, cheeks, eyelids, chin, jawline, and lips. Magnetic resonance evaluation was performed with the exception of lip patients who were evaluated with ultrasound. Postoperative follow-up was 12 months to 6 years. Subjective and objective methods were used for outcome evaluation according to the FACE-Q questionnaire. Functional and aesthetic correction was scored using the patient-graded Global Aesthetic Improvement Scale (GAIS), overall patient satisfaction was assessed by a five-point scale questionnaire. Functional and aesthetic restoration was globally recognized as improved according to the GAIS. Patients reported high levels of satisfaction assessed by a five-point scale questionnaire. A very good satisfaction level was registered in both subjective and objective judgment scores. To the best of our knowledge, we present the largest case series regarding surgical removal of permanent facial fillers. A proper preoperative evaluation, filler removal followed by restorative facial aesthetic surgery technique is paramount to approach challenging cases
Remodeling the neck and the lower jaw with Dehoxycholate injections
No full textNonsurgical cosmetic facial procedures have gained popularity in recent decades. These procedures are commonly referred to as facial rejuvenation, and only a few are performed in the neck region. Herein, the authors describe their experience with off-label use of deoxycholic acid (DC) injections on 18 patients for remodeling of the neck and lower jaw. The injection protocol was personalized for each patient, and lidocaine was always premixed with the DC. After the initial injection visit, at least 3 months passed before further injections were considered. All documented side effects, including swelling and dysesthesia, resolved spontaneously. All patients received follow-up for at least 3 months, and only 2 patients required a second session of injections. By personalizing the injection protocol for each patient, good outcomes were achieved, including aesthetic enhancement of the shape and contour of the jaw and neck. Although the study is limited by the relatively small sample size, the results are promising and warrant additional investigations
Surgical lip remodeling after injection of permanent filler
No full textBackground: A major concern regarding permanent lip fillers is difficulty with revision should this be required. Currently, the only way to treat lip sequelae is by surgical remodeling. Objectives: Based on the senior author's 6-year experience, the authors collectively suggest a surgical method to correct lip deformity in such situations. Methods: The records of 38 patients with lip deformity who underwent surgery between 2011 and 2017 after receiving permanent filler injections were analyzed retrospectively. A total of 38 consecutive patients (69 lips) with an average age of 38.8 years (range, 28-52 years) were treated surgically. Results: All patients experienced postoperative swelling (average duration, 15 days), and no infections were recorded. In 3 cases, a 1-cm dehiscence was documented, which healed by secondary intention. In 1 case, a hematoma noted several days after surgery resolved spontaneously within 3 weeks. In 2 upper lips, a minor touchup procedure (with the patient under local anesthesia) was performed 9 months after the initial surgery. Overall, patients noted that it took at least 6 to 9 months to achieve natural lip movement. The average time until softening of the lip tissue was 4 months. Conclusions: This study emphasizes the importance of informing patients that complete removal of permanent filler is not always possible. However, most of the authors' patients were pleased with the results. This study also highlights the importance of paying strict attention when approaching the area adjacent to the oral commissures in order to avoid potential reductions in mouth opening that can occur from postoperative scarring.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
